1) • Single +5 V, ±5 % power supply • 208-pin plastic quad flat package Line Transceiver Common Control Interface +5V 4 DESCRIPTION The DS1MX7 is a seven-channel byte-synchronous and asynchronous DS1 mapper.
Both SONET and SDH mappings are provided per Bellcore GR-253-CORE (VT1.
5) and ITU-T G.
707 3-96 (TU-11).
A single add/drop Telecom Bus is provided that can operate at either 6.
48 or 19.
44 MHz, which is compatible with other TranSwitch devices.
VT1.
5/TU-11 pointer tracking and overhead extraction/processing with full error and alarm control is provided.
VT1.
5/TU-11 pointer calculation and overhead assembly is also provided.
Alarm and error mappings from drop to add and SONET/SDH to/from DS1 are provided.
Jitter performance is achieved with a fully digital threshold modulator and DPLL that meets GR-253-CORE MTIE requirements without external de-jitter buffers.
For the DS1 line, AMI, B8ZS and NRZ line codes are supported with full alarm detection...
